Archived - Mac OS 9: Available Updates
This document describes the updates available for Mac OS 9, and the order in which they must be installed.
Mac OS 9.0, Mac OS 9.1, Mac OS 9.2
Tip: Mac OS 9 was a great operating system years ago, but there's so much you can do in Mac OS X that you can't do in Mac OS 9. Every new Mac comes with Mac OS X—or you can purchase it at the online Apple Store or your local retail Apple Store (Note: Not every Mac can start up in Mac OS 9 and Mac OS X. For more information, see "Some Computers Only Start Up in Mac OS X.")
|Mac OS 9.2.2
|Mac OS 9.2.1
|Mac OS 9.1
|Mac OS 9.0.4
You must install all prerequisite software before installing any update. To update Mac OS 9.0 to Mac OS 9.2.2, install updates in this order:
- Mac OS 9.1 Update
- Mac OS 9.2.1 Update
- Mac OS 9.2.2 Update
Important: You cannot upgrade any version of System 7 or Mac OS 8 to Mac OS 9 through a downloadable software update--purchase a later version in order to upgrade.
